I am experiencing a similar problem. Once I add in a second style for my song, the higher bank patches aren't executed. I can see the Bank0 value on that patch is correct, but bb plays the GM patch instead. If I do a quick Bank0 up then down (with the arrow buttons) to the original value, the correct patch starts playing. I can also define the correct patch using F5 (bar settings) every time the style changes, so I am not dead in the water, but I doubt that multistyles were intended to function in this way.

I'm using the Ketron SD2 and the associated .pat file. Is this happening with anyone else?
